There is no need for an entry on the paperwork for refitting cowls on a light aircraft purely and simply because the majority are maintained under LAMPS and item 3 on the LAMPS schedule states
3 Following ground run, ensure all cowlings, access panels and doors are secure. CHK All checks
Therefore in clearing an aircraft under the LAMPS schedule you are certifying the task has been carried out.
The CAA can be diabolical and the standards vary from excellent to dreadful amongst some Surveyors, yours obviously does not know their own Maintenance programmes or would be aware there is an entry in it!..
One of the classic cases to show the widespread differences in interpretation and quality was when companies moved over to EASA approvals, one just has to look at the types that companies are certified to maintain........
Some companies have had to list the likes of Cessna140 150 152 172 182 210 etc etc etc where others have been allowed to simply list Reims/Cessna singles below XYZ weight, the latter being the sensible way to do them.............
Indeed one company even had I believe Cirrus twins on their approval........ they might as well of had Rebel Alliance X Wing MK 1 on their approval, because neither exist in real life!!!
I am afraid the CAA has gone down hill rapidly in recent years, surveyors used to be people from the industry with a wide knowledge of aircraft and their systems, these days a lot of them are ex graduates who simply do not have a clue.... I despaired when I read through the original CAA Engineers guidance to licensing book, under type examples for holding groups they had
Cessna Metal Pressurised Multi
Piston Engined Aircraft
the two examples they listed being the
Cessna 550 ( CITATION JET!!!! )
Cessna 441 ( TURBO PROP!!!!! )
I have seen hangars where the CAA have moaned the floor is not painted, or the wrong colour!!!! or the paint is flaking, then I have been to hangars that have compressed earth floors and thought, bet they were never told to paint it!!
I have seen Engineers working on their own have to produce pie charts to show how they split up their day in the exposition or produce shift hand over forms to hand over work to other engineers even though he is a one man band................ so what the CAA does never suprises me these days.
